Detailed Discussions of Bit 1
Use it to enable/disable transmission of an echo protect tone for a high-speed transmission
V.29 modem signal (transmission speed at 9600 or 7200 bps).
If errors occur frequently at time of transmission because of the condition of the line, select
'transmit' so that a non-modulation carrier will be transmitted as a pre-image transmission
sync signal for about 200 msec.
Error Code:
Any of the following error codes may be indicated because of the line condition at time of
transmission
##100, ##104, ##281, ##283, ##750, ##755, ##760, ##765
Detailed Discussions of Bits 4, 5, and 6
Use it to select an appropriate transmission mode: international transmission (1), international
transmission (2), or international transmission (3).
Use the service soft switch or the dial registration function to select the appropriate
transmission mode if errors occur frequently at time of transmission to overseas.
Error Code:
Any of the following error codes may be indicated because of an echo at time of transmission
##005, ##100, ##101, ##102, ##104, ##201, ##280, ##281, ##283, ##284, ##750, ##760,
##765, ##774, ##779, ##784, ##794

Using the Dial Recognition Function (user level):
Select 'international transmission (1)' when making an entry in the Address Book. If errors
still occur, select 'international transmission (2)' and then 'international transmission (3)'
in sequence until errors stop. The transmission mode selected using the One-Touch Dial
function or the Speed Dial function will be give priority over the setting made by the service
soft switch.
An international transmission mode may be selected using the keypad if a mode has been
selected using this switch; for settings, see the following table:

International transmission (1): select it to ignore the first DIS signal from the other party.
International transmission (2): select it to transmit a 1850-Hz total signal when transmitting
the DIS signal.
International transmission (3): select it to transmit a 1650-Hz total signal when transmitting
the DIS signal.
Detailed Discussions of Bit 7
Use it to enable/disable transmission of a 1080-Hz tonal signal before transmission of the
CED signal.
Select 'transmit' if errors occur frequently because of an echo when reception is from
overseas.
Error Code:
Any of the following error code may be indicated because of an echo at time of reception
##005, ##101, ##106, ##107, ##114, ##200, ##201, ##790
